-To all whom it may concern:

Be it known. that I, Jenn H. S'rsvmzs, oi {lain bridge, in the county of Middlesex and State of Mus. chusetts, have invented certain new and useful I inprovements in Water-Closets, of which the iollowing, taken in connection with v the accompanying drawings, is a specification. p

My invention relates to water closets and especially to the construction of the earthenware portion thereof and it consists i certain novel features of construe tion, arrangement, and combination of parts which will be readily understood by reference to the description of the accompanying drawings and to the claims hereto appended and in which my invention is clearly pointed out. I

Figure lol the drawings is a sectional side elevation of a water closet bowl embodying my invention,

the cutting plane of the sectional portion being on line AA on Fig. 2. Fig. 2 is a sectional plan of the same, the cutting plane of the lower orv sectional half of said view being on line B-B on Fig. 1. Fig. 3 is u. rear elevation of the same. Fig. 4 is a vertica'. section on line (1-0 on Fig. 1 looking toward the right of said figure, and Fig. 5 is a partial vertical section of the same on line I -A 0n Figs. 2 and 3, and illustrating a modification of the construction of the ventilating pipe. i

Heretoiore water closet bowls which were provided with flushing rims have generally been constructed with a flushing passage and orifices therefrom extending entirely around (he seat-rcceiving opening with out extending around the air duct or ventilating passage, the result of which was that after the closet had been used and the water was turned on to flush the closet, the water dischargml into the bowl, nix fi ly or entirely prevented the escape oi the foul odors through said ventilating duct or passage, the sheet of water passing downward in front of said duct, nearly closing the some, at the very time when the contents of the bowl are being agitated and the ventilation is most needed. Another objection is that when little or no flushing oi the inclined surface of the wall of the rearward extension of the bowl. from which the ventilating passage opens, takes place, due to the small sprayingorifices arranged at the extreme rear and in the center of said extension, said inclined surface, which was readily seen from the front of the bowl. soon be came unsightly by reason of dust and dirt accurnulating thereon oii account of the draft oi the ventilating duct when the water is shut off.

The object of my present invention is to overcome or reduce to a minimum these objections and at the some time maintain the lull capacity of the vcntihting duct when the flushing water is being discharged inl'o tlle bowl, without increasing the length of the closet from front to rear.

To obtain these desirable ends I conslructcd the earthenware closet as illustrated i n the accompanying drawings in which 1 represents the bowl proper provided with the discharge passage 2 preferably arranged directly beneath the rear edge of them-at receiving openingthoreof. The bowl 1 is providcd'with an inwardly projecting flange or rim 3 and with the ventilating passage communicating with the top of said flange outside of the circle of sziid seat-receiving opening passing through said flange, as shown. The flange or rim 3 has formed therein the water passage 5 which extends around the front and sides of the bowl proper, and around the sides and rear of the extension 8 from which the ventilating passage 4 opens and communicates with the interior of the Water supply passage (5 on opposite sides thereof, as shown in Fig. 2. The flushing passage 5 is provided with a series of flushing orifices 7 of varying size arranged at short intervals apart through-- out the entire length of said passage and extending and its rearward extension is in close proximity to the inner surfaces of said howl so as to thoroughly flush the whole interior surface of the closet without interfering with free action of the ventilating duct.

The ventilating pipe 9 which covers the ventilating passage 4 and extends at any desired angle therefrom, is preferably formed integral with the bowl, as shown in Figs. l, 2 and 3, but it may he made separate therefrom, if desired, and secured thereto in any desired position by the crossbar 10 and clamping bolt 11, as ,shown in Fig. 5. Q

The howl Lhas formed thereon two integral cars 12- 12, one on each side of its rear portion outside of the flushing passage 5, each having formed them-through a vertical opening 13 to receive the fixed portions of the seat hinge, or a bolt therefor not shown. A flange 14 is formed around. the base of said howl by which it is supported in an upright position when set in place in a well-known manner. The water inlet passage has with, in any Well-known manner, a metal bushing 15 the outer end of which is threaded to receive the water supply pipe, not shown, said bushing being shown in Figs. 1 and '5 only.

By extending the flushing passage 5 around the front and sides of the seat-receiving opening and, sides and rear of the extension 8 without extending it around the rear of the bowl proper between the seat-receiving opening and the ventilating opening above the roan Ward extension 8 a chamber is formed between the inclined surface of the extension 8 and the curtain 16 which extends between two points of the inner Wall of the flushing passage 5 between the seat-receiving opening 4. A considerably greater area of ventilating space is thus secured thancsn be obtained when the flushing passage 5 extends around the rear oi the bowl between fitted therein so as to form a liquid Light joint there,

through its bottom wall into the interior of the bowl out in the least obstructing the escape of the foul odors through the ventilating passage when the flushing water is in full operation.

\Vhile the invention is illustrated as applied to a closet the discharge from which is directlybeneath the rear edge of the seat-receiving opening, it is obvious that my invention may be applied to closets of d i fl'erent terms without departing from the principles of this invention.

Having thus described my invention, 1 claim:

1. water-closet having a. single annular duct or passage extending entirely around the upper portion thereof just beneath the top plate through which the flushing wte ler is supplied to the bowl through a series of discharge oritiees arranged at intervals throughout: its length. and a seat opening and a ventilating opening both cut through said top plate within the perimeter of said pa. go.

2!. A watencloset provided with a top plate and having a single annular duct. or passage extending entirely around the upper portion thereof just. beneath said plate through which th finishing water is supplied to the bowl, a seat opening cut through said top plate. means for securing a seat to said top plate. and a ventilating opening also cut through said top plate within the perimeter of said pas sage but outside the limits of said seat portion in combination with a pipe extending upwardly from said ventilating opening and horizontally with its lowest: portion above the upper level of said top plate. I
